If your LLC has more than one member or employs anyone -- even if not full time -- you must request a federal tax ID from the Internal Revenue Service. Certain taxation decisions may also require you to obtain a tax ID. The number is also called an employer identification number and is the way the IRS identifies businesses on their tax filings. In this way, it is similar to your personal Social Security number. If your LLC is located in the United States, you may request an EIN online at the IRS website.
